The Solenoid Quick Release Mechanism MKII is designed to provide a simple electro-mechanical release mechanism for gravity-operated devices such as the Landon Kingsway free fall fire valve.
Landon Kingsway recommended the Solenoid Quick Release Mechanism MKII when the Solenoid Quick Release Mechanism is being used in conjunction with a sump switch.
Should the float switch operate due to the sump being filled with either oil or water, it breaks the circuit of the solenoid allowing the fire valve to close. The self-holding relay is also de-energised, which breaks the feed to the sump switch. The relay has back contacts which break on de-energisation, enabling remote visual and audible alarms to be connected to the unit. If a self-holding relay is not used when employing a sump switch, it does mean that when the sump switch operates, a live line is still fed to the sump switch which could prove dangerous if the boiler house were to flood with water.
The additional relay can be used on other applications where it is necessary to have remote indication of the fire valve operating, or alternatively can be used to operate further solenoid quick releases which may close or open the fire prevention dampers.
